I'm worried there's some disconnect between the AIC and Pawn for some reason when spawning

[runic parrot]

Reset the pawn rotation and try again, most likely it's that because you are using the respawn transform when creating the actor

[spring kayak]

Like, this is succeeding when the AI is placed, but failing when it's spawned

[open latch]

so after destroying the character > reset pawn rotation and then spawn?

[runic parrot]

how are you adding the AI? usually i spawn one AI when needed and then use it as a reference to posses a pawn.

[spring kayak]

I'm making an encounter with multiple waves of enemies

[runic parrot]

When spawning, make a new transform and split it, to that transform only add the location from the death spawn, let rotation and scale as default.

Wait, i just watched the script and you are destroying the actor and recreating it on itself? why not just change location of actor and reuse that one?

or let another actor handle that so you don't get references errors. Spawn the new actor first and then destroying the old one may work too.

[runic parrot]

hmm i'm not fresh on AI, i don't think i can help.

[spring kayak]

No worries, thanks anyway

[runic parrot]

from the looks of it, you are triggering one method on AI begin play

and trying to use one variable that is only assigned after the character is spawned.

Also the owner is empty on Spawn and is being used "on activation".

[ionic heath]

@spring kayak in character BP look for auto possess ai option in class defaults

[runic parrot]

One question, i'm adding a bunch of static mesh component to one actor in order to create a map.
I want a way to identify each static mesh later, does anyone know of a way to do that?

i tried using the display name of the static mesh, but i can't change it on spawn

[spring kayak]

@runic parrot I solved it! I had to change this setting to possess on spawn and also I had to set up the pawn from the actor instead of in the controller for some reason. I also added a small delay before running the behavior tree from the AI Controller. I'm so happy

[runic parrot]

nice

[open latch]

nothing worked 😛

[runic parrot]

Can't you just change location instead of destroying it?

[open latch]

I did

but it keeps its current forward vector even though the visually it is changed to its new transform

on spawn it is changed to its new rotation, but on input it is reverted

[runic parrot]

are you changing only the location or the entired transform?

[open latch]

location & rotation

[undone surge]

what is the benfeit of storing a sensed actor in a variable in ai perception

[cyan bone]

How do i use the vinterp to without any delay ? It keeps crashing if i remove the delay.

[odd ember]

you'll have to do it over time

so a timer or a timeline

or tick

if you are desperate

[cyan bone]

what if i have instances that i need to animate. should i still use a timeline?

[odd ember]

what kind of instances?

[cyan bone]

instance mesh

[fiery swallow]

put a 0.0 delay loop if you want to fire and forget, it'll give you the smooth result you want

[cyan bone]

But then that will cause issues in multiplayer, right? Because of frames?

[fiery swallow]

no, what you want to do is pretty simple

it won't cause any problems

[icy dragon]

At least this is not the top reason of me wanting to spank someone, Asian parent style.

[fiery swallow]

not sure what you mean, there is absolutely nothing wrong with using 0.0 delays fam

we can pull up the profiler right now

[odd ember]

it's not about performance, it's the fact that you're using it in lieu of better options

[open latch]

my logic works for mixamo characters that gets spawned but not for third person actor 😦

[fiery swallow]

There's always a better way to do things, but that's not stopping us from using hard references all the time, or casting when we really should be using an Interface 😄 . Just because there's a better way doesn't necessarily mean it's the wrong way

[brazen pike]

just because it's not wrong, doesn't mean its good

[odd ember]

you should never use an interface in lieu of casting

interfaces do a vtable lookup plus an internal cast

whereas the cast just does the cast

[fiery swallow]

We can go on all day about the right and wrong way to do things, and the best way to do something... but nobody's doing everything right, that's almost guaranteed. So there's no point in nit picking every little thing you can honestly. But to each their own 🤷‍♂️

[sonic crest]

Hello, quick question
so I have an actor as an NPC or "enemy" and it has multiple actors (these actors are the children of that NPC)
each of them have a different attack type, is it ok or smart to use the "Custom Event" on the main character for the chidren to use? those custom event on the main are empty, but they have code in the children actors

this is in the main actor

[odd ember]

well if you're going to come and suggest something as a valid solution and you're being questioned for it, you best have some good rationale for picking that solution over other, better solutions

[sonic crest]

one of the children

[odd ember]

what do you for yourself is whatever, but if you're teaching people the wrong things you are blindly leading others

[brazen pike]

Its probably fine, but if melee and ranged attacks are very similar for each child you should probably move the functionality into the parent

[sonic crest]

I plan to have the enemies to have different types of attacks, and even planning to add alternative attacks such as stomping and stuff (so also I'll use a Custom Event)

[odd ember]

tbh this looks like it should go into a state machine or a behavior tree

[sonic crest]

since this enemy predict it's target's movenemt and will shoot barrels if you are close to them, while another AI attacks the player on his position since he's a hitscanner

[fiery swallow]

Not true, He asked a way to do something and I gave him an alternative to what was already mentioned, and the reason for it was a simple and effective "fire and forget" solution. Nothing wrong with it

[sonic crest]

I was thinking about this, but haven't worked on a BT yet. just blueprints

so whenever I stop being lazy and decide to start experimenting on BT I will try it out

I was thinking of calling that custom event from the BT code

[odd ember]

it is true. while the quick and dirty approach might be with a delay 0.0 it's got a bunch of issues that you're not going to resolve. if it's multiplayer you're not going to ensure consistency. likewise if you've ever suggested something like interfaces over casts then you're in the wrong as well

[sonic crest]

like when the reactionTime reaches 0 and with other conditions met, it will launch the Ranged Attack event on that AI

[fiery swallow]

You know the difference between subjective and objective?

[odd ember]

interfaces have very specific use cases that they should not be used outside of

[odd ember]

yes, and you are objectively wrong

[brazen pike]

I think they meant using casts when you should use interfaces, as in the specific instances where that's true. I doubt they meant every time you use a cast you should use an interface

[fiery swallow]

like as you just said "this looks like something that belongs in a BT or SM" that's subjective, not objective. It's totally fine where it is, it's totally fine in a BT, it's totally fine in a SM

[icy dragon]

Timeline is a more reasonable alternative if you don't want to gatekeep Event Tick and it's rather fire and forget.

[sonic crest]

hmm

[odd ember]

there are very very few cases where you should be using interfaces, and interface abuse in BP is rife because people are being taught the wrong things

[sonic crest]

thanks for the help 🍻

[icy dragon]

Also I'm pretty sure Timeline is replicated in MP and not too dependant on framerate or much risk of overshooting

[sonic crest]

that's why I don't watch tutorials, I prefer experimenting myself

[brazen pike]

I suppose that's true comparatively, but using an interface to replace dozens of casts isn't exactly uncommon. Specifically interaction

[sonic crest]

I only watch when I am totally new to it, even tho I would do it differently

and get tips from professional people

I use Interface for interactions, I don't really use Casts except when I want some specific values

[odd ember]

this is strawmanning though, I don't know the context of the example you're saying. interfaces generally have one use: to bridge functionality across object oriented hierarchies. if you're not using it for that, then you're using it wrong

[fiery swallow]

You can "guide" these people however you like @odd ember but what you say is often your opinion. Don't pick fights with me because you think your way of doing everything is the best way

[sonic crest]

or something is intended for that thing

[fiery swallow]

Feel free to use the block button anytime you don't like what I say bud

[odd ember]

"well that's just like your opinion, man" isn't a valid defense for just blabbering nonsense. back up your opinion with an understanding of the technical side. I've done that. where is your rationale?

[sonic crest]

that's mainly use of an interface I use actually

[fiery swallow]

Grow up, I'm not gonna continue to argue with you because you're upset I gave someone an alternate option.

[icy dragon]

Delay as an alternative to Event Tick can be a bitch to get replication, and had more risk of overshooting the values
And I'm just using replication for futureproofing for replay system.

[odd ember]

if you think this is about you then you're missing the point entirely

it's about what you propagate to other people

[odd ember]

great rebuttal. if you could stay on topic rather than going the ad hominem route that'd be swell, thanks

[odd ember]

well you're in luck that you're using them correctly

[brazen pike]

My understanding is that interfaces are used when you want functionality to fire in one of a number of things, not really caring which one. But casts are used when you do care about what you're checking and want something specific. You'd cast to a controller, animation, etc. But you'd do an interface when you don't want to do too many casts in a row because there are many things you're checking for. I don't know technical terminology, but hopefuly that clears up what I mean

[tawdry surge]

I don't understand the logic behind worrying about the vtable look up..
It's one instruction (aka nothing) and every inherted blueprint callable event has one.
It's more about not making an interface when casting will do it fine.

[fiery swallow]

Totally, It's important to know when something is better to use then something else. But I don't agree it's it's a bad idea to always use a 0.0 delay node. Actually we use it frequently in our studio to get small things done without any problem.

[sonic crest]

^^

interactions, for example, buttons, cars, possessing...etc

[odd ember]

I outlined above the use cases for interfaces. that's the reason they exist. there are many cases in what you're saying where you could get away with cheaper, better options such as delegates/event dispatchers - which are often overlooked here

[sonic crest]

I've used it once

and I think they're used to continue a code or if it's waiting for somethiing to happen to continue

[odd ember]

I don't think anyone is worried about the vtable lookup. it's just a point that you hear often that you should be using interfaces instead of casting, and that line of thinking is wrong. again, interfaces have very specific use cases. outside of those you're better off using casts or event dispatchers

[brazen pike]

Hmmm I suppose you could use an event dispatcher, but then surely you'd run into the problem of only being able to send out a call from one thing, if you have multiple possible origins it might be easier to use an interface. But you're right, there are tons of possible cases so its just important to remember the main concepts

[odd ember]

if you have a many to many relationship, that sounds like there's something missing in the architecture to centralize that

[sonic crest]

that's the only time I used a dispatcher

and was just for experimenting and just left it there

not sure if it's correct but eh, it works

and only appears when the player dies

[odd ember]

I mean it works, but it's predicated on the fact that the widget spawns after the player spawns, for instance

[sonic crest]

yes true, but I left it there just because (of course later I will change it)

mostly was for experimenting with it and left it there

[odd ember]

well if you can assert that it will ever only spawn at a point where the player has been spawned (e.g. if the player actually spawns the widget), then it's fine

[hybrid orbit]

@undone surge#gameplay-ai

[odd ember]

there's a lot of conditional cases wherein if you can assert bad cases will never happen you can win a lot

[icy dragon]

I sure hope your game isn't a multiplayer nor having replay system (that do use demonet and in turn replication)

[undone surge]

srry i couldnt find ai channel last 2 days so i posted here. ill put it there

wait why is ai channel dissapearing when im in blueprint and blueprint dissapears when im in ai

i think my disc broken

[odd ember]

click on the small arrow next to "programming"

[undone surge]

aaah

thnx

[sonic crest]

new channels

[cyan bone]

This is so confusing to me, im sorry. I feel like i have lead in my brain
Im trying to make it vinterp to using a timeline to 5000. But it stops before always.

[odd ember]

the timeline duration is probably too short

[fiery swallow]

Of course it's multiplayer, and it's not my game sadly, I just work for the company. But we don't use it for things that would need to be synced up across the board. That wouldn't make sense given that a 0.0 delay node waits for the next tick.

[cyan bone]

Yes. Thats it. But how can i predict how much will be needed? Because it will change according to the situation. Is there a way to just make it unlimited?

[remote meteor]

hm you tell it how much time it should take to lerp form value A to B

thats the use of timeline

[odd ember]

you can use a timer instead in that case. or you could try with a lerp node instead

[remote meteor]

if you want a constant rate of change

a timer may be more suitable, or even a tick

[sonic crest]

never tried this but

[odd ember]

no need for hacky solutions

[sonic crest]

agreed

oh it doesnt event work

[odd ember]

even unreal realizes the futility of this 😅

[remote meteor]

you can ask a timeline to loop infinitely btw

😅

double click inside

[odd ember]

that is true, but the value will still reset

[remote meteor]

yeah

[odd ember]

I feel like I've had this exact conversation a few months back

[cyan bone]

Loop [X] ?

[remote meteor]

hm nevermind that

[odd ember]

yes

but again, your value will be affected

[remote meteor]

can you roughly explain what are we trying to do here?

[odd ember]

if you want infinite looping, a timer is a better alternative

[sonic crest]

timber by event

timer

[cyan bone]

In video tutorial i watched a few minutes ago. Im not sure if i got it very well. But he said that it suffers from the same problem of the delay, in multiplayer

im not very sure. but i was studying the timer before

[odd ember]

okay then describe your case. I generally would abstain from tutorials

[sonic crest]

get tips from tutorials, don't copy their work

[odd ember]

they will teach you the wrong things because the people doing them are doing it for the views/money, not for actually teaching you

most of them, anyway

[icy dragon]

If you're unexperienced there's no way to tell from charlatan YTers

[odd ember]

it's very easy to become a "blueprint expert" without credentials and act as if you know stuff and then just do random hacks in a youtube video

[icy dragon]

In the context of your project, what mechanic do you intend to get working with what you have right now?

[odd ember]

also generally only do this if you're at a level where you can tell whether they are hacking something together or doing it for realsies

[sonic crest]

exactly

[fiery swallow]

https://gyazo.com/1f6ba52d94fb433b621fe24f81e8f9b3

You can let these guys tell you the supposedly right way all you want. But this way should get you what you want, when it's time to optimize you can easily get back to it later

You'll learn better methods as you continue to program and pick things up, no need to stress for hours to accomplish one small task

[odd ember]

if you listened to what they said, they said they're not wanting to use timer or delay because of the issues with multiplayer

[remote meteor]

I think we probably can omit multiplayer problems since obviously we are not on the scalr

But doing that delay 0.0

[cyan bone]

Im moving instances. Everything is working with Delays. But i want to do it with timelines or as CE said Lerps maybe?

[odd ember]

I mean the above setup is the same as a timer set to frame time

but slightly more expensive due to the setup

[remote meteor]

Once you have a hitch in frames

Rip consistency

[icy dragon]

I'm sure the next reply would be "it works for me, my game is a multiplayer"

Which to be fair if it works for them, strangers on Discord won't have the authority to contest that in their own project.

[odd ember]

timelines with an alpha (0..1 value) into a lerp node will linearly interpolate from one point to another point

if you're e.g. doing door openings, it's one of the best use cases out there

[icy dragon]

Also it's consistent even in bad framerates

[odd ember]

"well if it works for me it should work for everyone! also I take no responsibility if you fail, bye"

[cyan bone]

Im animating spears back and forth in the direction of the enemies. Its so confusing.

[odd ember]

spears as in a static trap? or spears as in dynamic on a character?

[ruby glade]

ue 5.0.1 update breaks physics cables, anyone have problems?

[fiery swallow]

Nah you guys are just completely over complicating it, scaring beginner programmers. Making everything hard, and confusing

[cyan bone]

spears on characters moving against other characters

[odd ember]

I would handle that through animations

[ruby glade]

they are now very unstable

[icy dragon]

Making curves in timeline, yeah, that's the hardest and most confusing task ever smh

[odd ember]

have you consulted the physics channels?

[odd ember]

delay 0.0 or bust

[ruby glade]

i have just updated from 5.0.0 to 5.0.1 no changes were made

[cyan bone]

So no vinterp? But its an instanced static mesh?

[fiery swallow]

evidently it's hard if he's struggling to get it to work

[ruby glade]

i have just updated from 5.0.0 to 5.0.1 no changes were made

[odd ember]

I would say use sockets on the characters, attach the spears to the characters and let it be part of the animation

[earnest tangle]

Physics-using cables breaking?

In my experience they will break based on the position of the moon and the stars

:P

[cyan bone]

ok will do that. thank you all

[icy dragon]

No contesting that Delay 0.0 is way easier than using Timeline, or in this case, an animation.

[odd ember]

final stages of interview process at a company
"do you have any questions for us?"
yes would you ever use a delay node 0.0 for time delays?
"no we'd use timelines"
walks out of interview

[mental trellis]

Lol

[remote meteor]

Use the correct tools for the job

[fiery swallow]

Yeah great job though, you guys wasted an hour of his time trying to do something that he was never able to figure out, when the method I gave him would have worked just fine. In the end he ends up going with an entirely different method

great work

[odd ember]

except it wouldn't because you didn't listen to their problem. but yeah pat yourself on the back for that

[mental trellis]

What was the problem?

[brazen pike]

Dude asked for method that didn't impact multiplayer? You decided that they should have a way that impacts multiplayer. Of course everyone thinks thats not a good method

[odd ember]

spears moving with a character. they initially wanted to use vinterp to move the spears, but after it was explained that it was part of a character animation they went with a solution that allowed them to piggyback off of the animation movement

[mental trellis]

Attaching to a socket or something?

[odd ember]

yep

[mental trellis]

Surely that's the obvious answer to anyone who's used UE before?!

[odd ember]

you'd think that, but apparently we must use delay node 0.0 or we're dumdums

[fiery swallow]

we didn't know what he wanted until way later

he gave more detail much after my response of 0.0 delay, this weirdo left it out as if I responded 0.0 after he mentioned the spears on the character

[odd ember]

they also gave more details before you gave your solution for why delay 0.0 wouldn't be a good idea, but hey let's ignore that

[fiery swallow]

Wasn't here for it

I seen he had a problem, I offered a solution, and you threw a fit lol

[icy dragon]

More like you jumped the gun with the trusty delay 0.0

[brazen pike]

You also continued tod defend your solution after he said he'd go with something else, after he gave all the information and only just now going back on it

[fiery swallow]

this discord channel will soon turn into stack overflow nightmare with people like you ruling over it

[odd ember]

okay buddy

[fiery swallow]

you'd fit perfect a stack overflow mod dude be honest

downvoting and removing everything that disagree's with you

[icy dragon]

It wasn't until we probe for in project context that it came to light for the solution.

But nope, you went ahead with Delay 0.0 supremacy.

[odd ember]

you got multiple people disagreeing with you, trying to rationalize why your solution wouldn't work and yet you go on with ad hominem

maybe I don't know... just let it go?

[remote meteor]

Hey lets not suppress it with number but, if we are not sure about the asker's context

We can always just ask about it

😅

[odd ember]

clearly that's too easy

[chilly yarrow]

Hey guys. Quick question. I'm following UE4 tutorial in ue5 and the commands Vector * Float and Vector + Vector aren't available. What do I use instead?

[odd ember]

they have been consolidated into a single node

[remote meteor]

Hm use the universal node

You can plug them in

[tawdry surge]

Add @chilly yarrow

[remote meteor]

Add and multiply

[tawdry surge]

Or multiply

[icy dragon]

For context, in UE5, all basic math operator nodes have been consolidated to universal node.

I think comparative nodes like equals as well

Though it does have some setbacks compared to ye olde ways in UE4.

[chilly yarrow]

Okay. Thanks for the quick responses guys.

Does the structure of the code change? I copy and pasted the code I made in ue4 to ue5 and it doesn't seem to translate exactly

[remote meteor]

I think that part you need to replace them manually

[icy dragon]

Shouldn't change that much apart from the math nodes and custom functions with object reference inputs

[mental trellis]

What does a delay 0.0 even do, effectively? Just activate next tick?

[chilly yarrow]

Alright. I'll experiment a little. Thanks again 🙂

[remote meteor]

Yeap

[tawdry surge]

Short cuts the infinite loop error since it technically stopped

[mental trellis]

Ah. The loop count is pretty "small" from what I remember? Like 10k or something?

[remote meteor]

I don't think that count is ever accurate

😅

But yeah something like that

[odd ember]

~300k or so

I believe

[remote meteor]

You can set it in project setting

[mental trellis]

Not so small then.

[icy dragon]

Yes, and it's just as not elegant as using looping timers with small value because "Event Tick is bad"

[tawdry surge]

Everything is bad

[remote meteor]

I would like more control i guess

Unless you control your flow tightly else its easy to call it twice and unexpected behavior can happen

[fiery swallow]

It waits until the next tick, I initially offered it as a quick way to prototype what he needed as we use it just fine in our multiplayer game with no issues, Admittedly it is wrong for what he ended up wanting. But in that regard we were all wrong, what he needed was the socket attachments. Oops

[mental trellis]

Much like a toilet, well designed flow is usually a prerequisite of a good program.

[odd ember]

petition to rename the role of "blueprinter" to "plumber"

[dusk flame]

Hello friendly people! I am wondering if it will be possible for me to "capture" calls to SetActorHiddenInGame inside of Blueprint?

I have some issue where a BP asset should be hidden, but is instead invisible.

Thus I would like to see which calls are setting actor visibility.

[mental trellis]

Use VS it's simple!

[dusk flame]

I know I can do this with an actor child-class in C++, but I was wondering if it's possible BP for quick testing

[mental trellis]

(or Rider)

[dusk flame]

You can debug a blueprint asset in Rider?

Sounds like a good skill to learn haha

[mental trellis]

You don't need to use a child class in c++, you can breakpoint the engine method

[icy dragon]

As if being an electrical engineer wasn't enough smh

[dusk flame]

Does rider have conditional breakpoints?

[mental trellis]

Yes? I think?

[tawdry surge]

There is a BP call stack

[dusk flame]

Because if I breakpoint that method, it's going to get hit a LOT

[brittle garnet]

Yes. Right-click on the breakpoint to bring up options.

[mental trellis]

You could add a log call to see the actor it's being called on and the value of t/f

[dusk flame]

This is a replication issue, in case anyone was wondering. UE4 should replicate the visibility state natively (see rep condition on the prop), but it's not replicating if I call SetActorHiddenInGame too early

[mental trellis]

"too early" ?

[dusk flame]

Within a couple of seconds after BeginPlay

My assumption is world load -> I call setHiddenInGame -> replication from world load arrives, overwriting my call

So maybe I actually need to debug the onRep method for that property.

I can always call setHiddenInGame on all clients + server, but for replicated actors that's technically double-replicating a property UE4 is already handling.

[dusk flame]

Wow! That's very useful. I hadn't realized Rider had that feature.

[mental trellis]

It really shouldn't overwrite replicated properties.

"shouldn't"

[dusk flame]

You mean, I shouldn't worry about setting replicated properties on client?

My assumption is that for a replicated actor, that I only need to switch state on the server (for replicated properties ofc)

[mental trellis]

What I mean is, if you set hiddeningame to true on an actor in the map, loading the map on the client should happen before any replicated properties are replicated.

Or it's kind of a shit system.

I can't believe Epic would do that.

[dusk flame]

Ah! This is an interesting point.

OK so I have an Actor, which is visible be default, and I'm hiding it, using some BP logic that runs roughly on BeginPlay (a bit after)

I wonder what happens if I make it invisible by default

Probably that state persists, and my server-call is still thrown away? But it's a good test.

[mental trellis]

It should replicate the changed property to the client

[dusk flame]

Yeah that works ""as expected""

[mental trellis]

Well clearly not lol.

[dusk flame]

The status of the actor checkbox "is Hidden in Game" is overwriting my call to SetActorHiddenInGame

I mean both directions are consistant.

So it's likely I just cannot rely on the server to replicate this property

It's not the end of the world to call it on clients, it's just an unwanted replication cost

[mental trellis]

Replication doesn't happen in both directions. Only RPC calls go from client to server.

[dusk flame]

Right now I'm only calling it on the server

And letting UE4 replicate the property to other actors

You can see in C++ that it's a replicated property, with an onRep

If I call setActorHiddenInGame after a 10 second delay, it works as expected.

[mental trellis]

It might be that the actor isn't relevant to the client at that point, so properties aren't being replicated for it.

[dusk flame]

Hmm

Maybe

But it's still a bit weird

[mental trellis]

That would be entirely expected behaviour if it's not relevant, I think.

[remote meteor]

i believe its overriding because the is hidden variable is being replicated by default

your set is called faster than the replicated value

so it kinda "overrides"

then the delay makes it "works"

[mental trellis]

I'd take a look at the state of sethiddeningame on beginplay on the client and for any onrep calls of hiddeningame

[remote meteor]

something like that

[mental trellis]

And also check that your blueprint isn't running on the client as well and unhiding it locally after replication has happened.

[dusk flame]

Yeah I think this is correct

[remote meteor]

maybe you can try the construction script ?

[dusk flame]

Although UE4 replication shouldn't exactly allow this to happen.

I guess that's the penalty of replicated properties Vs. RPCs.

[remote meteor]

hmm but that would make it hidden in editor too😅

[mental trellis]

Are you sure this isn't happening?

[dusk flame]

In general yes, I'm sure.

I have logic that deals with both Replicated and Unreplicated actors.

Unreplicated actors must have SetHiddenInGame called on both server and client.

[mental trellis]

I'd test your logic.

[dusk flame]

So I've added now this "optimization" for replicated actors, and it's broken if called too early.

[mental trellis]

Add a debug string to your bp and see if it's called on the client

[dusk flame]

I wonder if turning tick off disables replication 😮

[mental trellis]

It shouldn't.

[dusk flame]

So I'm definitely not calling SetHiddenInGame on the client

I mean, I do for unreped actors

But not for replicated ones.

[mental trellis]

How did you check?

[remote meteor]

hm i did some brief checks

should work just fine 🤔

[dusk flame]

I mean it's a single if statement 🙂

[mental trellis]

So you didn't check?

[dusk flame]

I mean I can place a breakpoint.

[mental trellis]

Did you add a debug string? Breakpoints can fail if you don't have the right instance selected (I believe?)

[remote meteor]

blueprint breakpoints can sometime fail outright 😅 i face that alot in 4.27.2, will need to restart editor

[dusk flame]

OK, I've noticed something funny though. Will need to dig deeper.

You're likely right something is fishy on my end, rather than UE4 being broken 🙂

[remote meteor]

good lucks 👍

[mental trellis]

He totally added a debug string and it fired on the client, I bet!

[remote meteor]

multiplayer can always find some way to screw my mind

[dusk flame]

No, I didn't.

But I did add a debug point, and it's not getting called. At all :/

So whatever I think my code is doing, it's not doing that lmao

[mental trellis]

Don't rely on breakpoints!

[dusk flame]

It might be a Rider bug though

It's a C++ breakpoint

[mental trellis]

Oh in Rider? Hmm.

It might be a separate instance it's opening so it's not debugging it.

[dusk flame]

Either way something is very fishy. I need to do some investigation. If I do track it down to UE4 replication issue I will let yall know 🙂

OK rider is smoking something

Breakpoint isn't hit, but a breakpoint further up is, and stepping down one call at a time, I eventually reach my original, unhit breakpoint.

So the code is definitely getting executed

[remote meteor]

the symbols got some issue i guess

[mental trellis]

Development mode?

Or Debug mode?

If you're using a prebuilt engine, it'll be Development and your breakpoint may not be hit properly.

[dusk flame]

I was in Development Editor

Maybe Development Game is better?

Also: To the point about the SetHiddenInGame probably being called on the client, this is sort of a miss, because when it's called on the client, then ofc it works.

[icy dragon]

DebugGame might be better option

[dusk flame]

But that's just circumventing the replication that UE4 is doing.

[dusk flame]

Does that keep more of the symbols in?

[icy dragon]

Probably, heard DebugGame config is even more "exposed" than Development, but I have yet to encounter a scenario where I absolutely need to build in DebugGame myself

[dusk flame]

It takes a lot longer, sadly.

I don't have a good mental picture yet of which each compile target does. I wonder if there is a list somewhere.

[remote meteor]

i recall a somesort of a lamba function that i cant manage to get a breakpoint off

but thats engine code, maybe i dont know how

🤷‍♂️

[dusk flame]

But the break-point is definitely getting missed, so I need to try something else

[mental trellis]

You want Debug Editor.

[dusk flame]

I think that's what I used to use, I can't recall why I would have switched it.

[mental trellis]

That builds both the engine and your game in Debug configuration.

[dusk flame]

So Debug Game might be fine in my case

Since I'm not really debugging engine code

[mental trellis]

Well that might be why your breakpoint isn't firing in the engine code.

Unless you created a new c++ actor in your game and are using that.

[dusk flame]

Breakpoint is in my own code.

[mental trellis]

Well, you're good then using Debug Game Editor!

[dusk flame]

Yeah I was using Development Editor

Some branches get trimmed out then I believe

I will do Debug Game, it should be a bit faster to compile.

Although it's taking its sweet time

[stoic zenith]

hey guys, does anybody know how can i implement proper gravity gun?

1. i can ofc do SetActorLocation with Lerp in Component Tick, but i guess there are some problems like teleporting through walls and preventing it (setting Sweep to true i guess won't work maybe i'm not right)

2. i also can Add Force to Skeletal Mesh Component of Actor i want to grab, but it feels hard to recalculate force

if you would implement gravity gun yourself, what would you choose?

[remote meteor]

sweep should work

depends how "absolute" the gravity gun should be

if it is very "absolute" addactorlocation should be okay

i would use a timeline for the sucking action i guess

[wheat cloud]

maybe a noob question , but why would you have negative value of weight for an animation curve

[sly relic]

I would look into using a PhysicsHandle component, it's what I used a few years ago when I tried recreating the gravity gun.
This is a bit of an older video, so hopefully it isn't outdated https://www.youtube.com/watch?v=OltZ-xFz8IQ

[stoic zenith]

thank you

[odd ember]

since you're writing code, why aren't you asking in #cpp ?

[stoic zenith]

this question is easy to understand for anyone unfamiliar with cxx so i asked it here >:(((

[dusk flame]

Maybe so, but Blueprint is for Blueprint, not code.

[odd ember]

I also doubt that anything involving physics is "easy to understand"

[dusk flame]

Maybe bigger issue is you asked, and got ignored?

Frustrating, for sure, but not something you can help by asking in wrong channel.

[stoic zenith]

message is edited now

[stoic zenith]

but i wasn't ignored

[dusk flame]

By gravity-gun, you mean like long-range grabbing of an actor, that should be physically simulated?

i.e., bumping into walls etc?

[remote meteor]

a gun that goes succc

[stoic zenith]

yes 🙂

[stoic zenith]

exactly

[dusk flame]

What should the behavior be in this scenario:

[remote meteor]

basically suck actors towards a single point in space

[dusk flame]

Are you accepting the 'beam' to travel through solid objects, as long as the grabbed object isn't obstructed?

[stoic zenith]

i guess it continues sucking object but it couldn't suck it because of the wall (it's not good but it will work for me)

[remote meteor]

sweep from the set/add location should work

[dusk flame]

Yeah

But it will snap back and forth along the surface

[remote meteor]

i think it would just stop there 🤔

[dusk flame]

A sweep will act like this

Sometimes desired, often not.

It will make object "jump" a lot forward and backward, depending on where you're pointing.

[stoic zenith]

i coded it but it's buggy and if i touch the player with grabbed object he flies the fuck away xd

will try using physics handle rn if distance towards the object is small enough

[remote meteor]

hmm things shouldnt fly away though

[stoic zenith]

idk i guess maybe collisions with teleportations with passing impulse to player work weird alltogether, but ok, anyway rewriting it

[remote meteor]

unless your actor are physics enabled then yeah you should use physics based if that is the case

[digital lantern]

Hi guys, I'm looking for a wave system where I can decide what to put in certain waves and the number, if you have an old project lying around... or a good YouTube tuto that works feel free to PM me or ping me, thanks a lot 🙂

[serene crown]

Hi, sorry for the abrupt entrance but I'm in a game Jam that ends in a few hours and Badly need to "Add C++ source files to the project from the Editor before you can generate project files"

Anyone know what I'm supposed to do? :/

[dark crow]

Add a C++ class to the project if it's Blueprint only

[serene crown]

I just tried that... Unreal crashed and now it's saying this:

I didn't change the engine version

only use unreal 5

[dark crow]

Do that then

You have a IDE no?

[maiden wadi]

if I recall, there is no way to change a BP project to a C++ one in UE5 at the moment. At least that was the answer I got when I started messing with it.

[serene crown]

So my game is just dead now? o.O

[maiden wadi]

Dunno. Just giving the answer I ended up on. I restarted my project, but it was about twenty minutes old.

[hot lotus]

No it's ok, just create a c++ file (even empty)

Oh sorry did not see the last message

[serene crown]

I tried that and now I can't even open anything anymore

[hot lotus]

I did it without issues on 5.1

Do you have an IDE?

[serene crown]

I also getting this now:
not possible to find any compatible framework version
The framework 'Microsoft.NETCore.App', version '3.1.0' (x64) was not found.

• The following frameworks were found:
  5.0.0 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  5.0.8 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  6.0.4 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

even tho I have it -_-

I'm just needed to do one thing... been working on this game for a game jam for the past 3 days non stop and now this... my spirit is crushed... 😦

[hot lotus]

Open the .sln with your ide and try to build it

It should be ok

[serene crown]

How do I do this? I'm very new at this :/

[hot lotus]

Go to the windows explorer folder of your project

In this folder there should be a .sln file

With your project name

[serene crown]

I find a .uproject file and a CPP, C or even ini files... but nothing with .sln

[hot lotus]

Right click on the uproject and generate files something?

[serene crown]

Yeah, it made the SLN file

[hot lotus]

Open it and there should be a build somewhere

[serene crown]

it's loading for days right now, but at least it's doing something 😛

[serene crown]

Build solution?

[hot lotus]

Yes

[serene crown]

We're back in business... thank you so much 😄

[hot lotus]

Good to hear

[manic hamlet]

Hey guys, ive got a Widget Bluepint..lets call it W_Button.
I have another Widget Blueprint(W_Main) that implements this button.

Now I would like to have a reference inside the Button-Widget to the W_Main Widget So that if I hit that button I can RemoveFromParent the W_Main Widget. How do I do that 😄 Probably a newbie question,but I am one LOL

hm,let me check..sec 😄

okay, I basically get what you mean, but how would I "sign up" for that button click event? cause If I click on the W_Button inside the W_Main all I can do is

This is basically my strucutre I have here:

[radiant mural]

Can anyone point me to an example of Equipping different armor type based on race/gender? Basically i am looking for a BP of a simple way to determine which armor to equip based on variables

[desert juniper]

Here's an approach
Have an enum that lists all possible Races
Have another one that lists all possible genders
Create a struct called something like 'EquipRequirements'
In there add an array of accepted genders, and another one for accepted races
Then simply add a 'EquipRequirements' variable to your Item

Now when Equipping, simply check that the character's race & gender matches with one of the items required acceptable race/genders

[manic hamlet]

@trim matrix

[radiant mural]

Interesting. Thanks! THat may work just fine

[manic hamlet]

what is wrex? XD

?!?!?!

[manic hamlet]

I guess. Pretty helpful to make fun/jokes that noone knows whilst someone is totally new to something and trying to figure out if that "joke" is actually part of the help or not.

[desert juniper]

Says someone that has that avatar 🤷‍♂️

[manic hamlet]

hm?

[rose charm]

Hello I have a floating platform that simulate physics, this platform can move and the player can walk on it, but when it is moving it keeps going down when the player is on it, what can I do to stop the platform getting pushed down by the player?

the collision, the player can build on it and move it, so i'm using the physics to update the collision when attaching other actors

[sick sapphire]

the 2sec is basically the reload time before the gun actually executes the load ammo logic.
i want to have a custom event that can Cancel the reload, so basically stop the delay and everything after it from happening

how do i do this

[remote meteor]

use a timer instead

you can cancel from the timer handle

[sick sapphire]

yeah but i thought there might be some logic error as some variables may be changed and line of code may need to be executed again within 2 secs

will try the timer and latent action method though

[hollow gorge]

How can I see the variables and functions of the parent class within a child class blueprint? I only found "Show inherited variables" so far but nothing for functions...

[tight schooner]

You can override a function/event and include a call to the parent function within the override, but I don't think you'll be able to see the original code without opening the parent class

[hollow gorge]

would it make sense to put the parent functions in a function library instead?

[tight schooner]

To see the parent functions as a list I guess you have to click the Override button on the UI

[trim matrix]

hey guys
Im trying to get a variable created from my animgraph into my controller

but I keep getting this error

basically if the Boolean is true it will play a small animation
the animation is not playing at all

[tight schooner]

Not sure what your goal is. The nice thing about inheritance is you have some control over where functions can be used (flowing down to children and being callable from the outside unless marked as "private" or "protected" e.g.) @hollow gorge

Function libraries are nice for truly universal things

[trim matrix]

what cast do i put in my controller if I want my character to perform the animation

[hollow gorge]

In my case, I made a parent widget class which holds the functionality to select and deselect keys (functionality + visually) in a widget. I wanted to make make a "MainMenu" or "SettingsMenu" that inherit this functionality. Would it make sense to use function libraries for this or would it be better to just keep the functions on the parent?
Edit: The parent also holds some variables like button array, target index etc.

[trim matrix]

because before the AI can run after me I want it to play a small animation @trim matrix

so what do i do

[tight schooner]

It depends how universal it is. If it's something you can picture a disparate smattering of actor classes using then yeah. If it's something that only pertains to a branch of classes in your class hierarchy then... You should try to put things where they "belong" so that your code makes sense as your project becomes more advanced.

I haven't messed with widgets that much, but if class hierarchies are possible, and if it sounds like a family of widgets could use that functionality, then maybe it belongs in some parent class.

[zealous moth]

how are you triggering the AI to chase?

AI component?

i mean if you just want to change animation, just use the Anim BP and create a state where the animation goes from whatever -> the anim you want to play -> chase state

[hollow gorge]

Ok thanks, that helped

[zealous moth]

@trim matrix where is your cat????

aw 😦 it was the cutest thing

[trim matrix]

ai perception

[trim matrix]

i did that

[zealous moth]

show me anim BP

[trim matrix]

<

[zealous moth]

with the states

[languid quail]

im trying to let a car follow a spline, and have its wheel correctly animated
so far everything works fine except the turning aspect

but obviously this doesn't work as its just getting the local rotation, not the rotation in relative to its original path
how would i go about that?

[zealous moth]

dot product of the forward vector of the car and the tangent of the spline at point x?

[languid quail]

i see thanks i will try that, thought about something like this but haven't made much with dot product yet

[zealous moth]

anything related to physical space should use the dot product

probably the most important operation

anyone who disagrees is wrong

[manic hamlet]

Hey, ive got a Widget Bluepint..lets call it W_Button.
I have another Widget Blueprint(W_Main) that implements this button.

Now I would like to have a reference inside the Button-Widget to the W_Main Widget So that if I hit that button I can RemoveFromParent the W_Main Widget. How do I do that 😄

With the click on W_Button I would like to close W_Main (RemoveFromParent)

Thanks for you help in advance 🙂

[zealous moth]

why not put remove from parent within W button once all the logic is done? @manic hamlet

[manic hamlet]

@zealous moth Thats what I am asking for 😄 but I dont have a reference to W_Main within W_Button 😄 thats what I am confused about ^^

[zealous moth]

get parent

[manic hamlet]

That removes the button itself only

[zealous moth]

get self ref-> get parent -> remove from parent?

[manic hamlet]

testing

Nope,let me give you some screenshots so you can "understand" what Ive got:

This is the W_Main

[zealous moth]

k

[manic hamlet]

This is the W_Button:

[zealous moth]

ok....

and the behaviour you want is...?

[manic hamlet]

If i click "Character1" button I want the W_Main to be gone, its basically going to be a character select window

with this:

[zealous moth]

add this to your button press

what does it print?

[manic hamlet]

Only the P_Characters is gone.

[languid quail]

when doing it without the multiplication the value i get is even in sharper corners something around 0.0001
but a multiplication seems like i am doing something wrong somewhere else

[manic hamlet]

Funny enough...an Empty string xD

[zealous moth]

no no

remove all logic

just keep print string

when you press the button, make it print its parent

[manic hamlet]

like this?

[zealous moth]

remove remove from parent

[manic hamlet]

ah yeah,ofc..lol ^^

P_Characters

As expected as thats the thing thats being removed

[zealous moth]

uh what?

[lament ginkgo]

Is there a way to spawn an actor into a folder in the scene outliner with blueprints?

[zealous moth]

get the other parent

[lament ginkgo]

I know you can do it in C

[zealous moth]

and so on

[manic hamlet]

@zealous moth So we basically need get one "level" higher to C_Main

[zealous moth]

that's how parenting "works"

[zealous moth]

Other than making your own logic to do it, I don't think there is an out of the box solution. Maybe some free widget in marketplace?

[lament ginkgo]

I looked into that, didn't find anything 😦

Seems like an odd feature to not expose in the blueprints.

[manic hamlet]

@zealous moth Now this prints C_Main but it doesnt remove the widget?!

Aka it is printing the right Widget I want to remove

[zealous moth]

You know what I misread, did you mean this???

[languid quail]

when im connecting the X axis i get the same problem, when using all axis my wheel gets crazy

[zealous moth]

use a print string to check the value of your dot product. The expectation is that if you are facing forward, it is 1. If you are 90 degrees left or right, it is 0 and if facing backwards it is -1

in between it is [0,1]

you use this as a reference to how much you are facing forward

the direction might be skewed. if your vehicle is rotated towards Y, you may need to adjust

[languid quail]

the group i get the rotation from is zeroed since its in local space
i will make a straight path and see if its something like 1 or close to 1

[zealous moth]

hm try world space

[zealous moth]

doesn't seem possible oob

[languid quail]

but you may be right when its driving completly straight is zero

[zealous moth]

then it means there is a 90 degree rotation :/

[manic hamlet]

@zealous moth Any new ideas for this? we print the right Name now...aka C_Main.. but it doesnt remove it with the BP above 😦

[zealous moth]

it technically should unless they made it so that children cannot kill parents.

in which case, make the function in your parent

[manic hamlet]

Pah..it works IRL.... 😄

[zealous moth]

and make your child cast to its parent

and then call it

[manic hamlet]

sry i like dark humor hihi

Hm,let me try that... im pretty new but i think i know how to cast to parent...lets see 😄

[remote meteor]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/EditorScripting/ActorEditing/SetFolderPath/

only available in development builds.

[zealous moth]

no friggin way!

[remote meteor]

or maybe that sets

the asset folder instead

i have no idea

probably used for editor blutilities

there is a way to get spawned actor to be "grouped"

you can attach them to an actor

and they will "grouped" under that actor

[final storm]

is there anyway to see splines in runtime or to check if they are there ?

[manic hamlet]

@zealous moth Well.. I thought I knew.... 😄

[languid quail]

yeah than my offset grp is messing this up

[final storm]

i'm trying to spawn a spline then add points to it in runtime

[remote meteor]

by the way

GetParent

is not get parent user widget

its the parent of the hierarchy

say a SizeBox containing ur User Widget

[manic hamlet]

Im open for alternatives 😄

[remote meteor]

GetParent on UserWidget gets you SizeBox

[manic hamlet]

Ah,so you never get "UserWidget"?

[remote meteor]

not the UserWidget the SizeBox resides in

i guess if you want

you can do event dispatcher

relay the message up to the parent

and remove itself

[tight schooner]

Probably not. I suppose you'll have to show them indirectly whether via spline mesh components or by spawning debug spheres (it's a node) all along the spline, or something.

[manic hamlet]

Unfortunately thats something ive never done :S

[remote meteor]

are these child runtime created widget or already placed in designer?

[zealous moth]

try this @remote meteor @manic hamlet

[remote meteor]

uh hm

UObject's outer eh

let me see

[zealous moth]

yeah, would need to use it as a parent style

[manic hamlet]

nope 😄

[remote meteor]

you need to cast

[zealous moth]

yup

but works oob

[manic hamlet]

cast as W_Main?

[zealous moth]

yes

so in your case, do it twice

like you did with parent

should get you the object

[trim matrix]

Hey

[zealous moth]

hey

where is the animBP?

[trim matrix]

Ill show my anim bp soon

[zealous moth]

where is it?

[trim matrix]

Something came up

[manic hamlet]

OHHHHHHHHH

I think we got it.... let me hook up the rest of da codes

[remote meteor]

nope

[manic hamlet]

@zealous moth My hero ❤️ Youre my batman now woop woop

[remote meteor]

outer is GameInstance

[manic hamlet]

nah,it works!

[zealous moth]

ok, someone is doing something wrong

lol

[manic hamlet]

The newb is doing it better ahn you @remote meteor xD

Thats the Final code..although I could get ride of the print stuff obviously 😄

[zealous moth]

do get outer 1 more time

[manic hamlet]

Well he only needs to get outer 2 times if he got it nested as I do

But he doesnt

[remote meteor]

nice parents

[manic hamlet]

He only got "horitontal box

[zealous moth]

??????????????????????????????????

what the heck

do 1 more 😄

I wanna see what contains UE

[manic hamlet]

HAHAHAHA

Hacking UE XD

[manic hamlet]

LOL

[remote meteor]

thats the last

[zealous moth]

holy sh*t what is this function?!?!!?

[remote meteor]

https://media.discordapp.net/attachments/296167427652321302/739088360596963368/emote-1.gif

what ue version u using btw?

[zealous moth]

you can also call the container that holds the widget

ue4 4.27

[manic hamlet]

5.0.1

[remote meteor]

4.27.2 here

[manic hamlet]

Im learning...so why not go with the new stuff 😄

[trim matrix]

You can just create a variable called OwnerWidget inside the WBP widget. In the variables details, set it as instance editable, and expose on spawn.

Then when you create the child WBP Widget, you can set that variable

[zealous moth]

but he manually put the widget, instead of having 1 mega interface or spawning it

[manic hamlet]

ISaka is just "testing" stuff for me. My setup is the "real" one..just fyi 😄

[trim matrix]

It looks like he is running The CreateWidget node.

Oh I see

[zealous moth]

yeah best way would be to have it all in 1 widget or have it spawn when needed

[manic hamlet]

My Setup is Got a W_Main and a button called W_Button and i put the W_Button inside the W_Main via Designer

[zealous moth]

there was a way, i forget how, to specifically cast to whatever is containing my widget, not necessarily the parent

[manic hamlet]

Well I will have to change it in the future anyway. Cause these buttons should be created on runtime depending on what characters the player has on the server but thats fuuuuuuuuuuuuture talk

Especially cause I cant find someone that knows how to read data from Json Files 😦

[remote meteor]

oh well

just another thing that epic decides consistency isnt needed

[remote meteor]

you need to know what type of panel your parent is to cast

the Slot As functions

anyway

if you place ur widgets within the designer

its Outer will be a WigetTree, and its Outer will be the Parent UserWidget

if you construct the widgets and add it to some hierachy

The Outer will remain game instance

since you usually dont update Outer

[manic hamlet]

Yeah but only if i add a 3rd outer 🙂 wich I dont need ^^

[remote meteor]

Outer's usage is for the level to know what UObject to be cleaned up

[languid quail]

i figured out that my X Axis for the calculation is wrong since its always 0 but using the Y Axis i get the rotation of my Car which seems more like what i should get rather than 0

[remote meteor]

also

jank af

and if your widget is placed in the designer

just place an Event Dispatcher in the child

click in to the parent

[manic hamlet]

@remote meteor
The Red marked stuff is W_Button

[remote meteor]

add the event

[trim matrix]

There is also functions you can override.

Maybe check the function overrides on that widget

[manic hamlet]

I dont know what Event Dispatchers are Im new 😄

[trim matrix]

They are very helpful

[remote meteor]

And you are not here to learn?

[manic hamlet]

Oh I am 😄 Right now im happy that it works 😄

And ive seen an Inventory Tutorial that i will start tomorrow with this Event Dispatcher thing..so I guess ill learn about it 😄

[full timber]

Can anybody help me understand why my inputs wont set boolean variable? I can hold left shift all day long and it wont set the variable to true. What am I doing wrong?

[remote meteor]

is the event being fired?

[desert juniper]

could be something else is consuming your input (or whatever BP you have there isn't set to receive inputs)

select the left shift node and press F9

this will set a breakpoint on it.
Then press play and press Shift

Does it stop the game, and navigate to the BP with the breakpoint?

[full timber]

the F9 did not do anything when I play the game. The variable still remains false. It also doent matter what input I use, I have tried LMB and a few others.

[remote meteor]

are you possessing the actor?

[desert juniper]

Then likely the BP isn't set to receive input. What is this BP?

[manic hamlet]

Wait, Ive tried this and this looks interesting, but after I added a "Event Dispatcher" i can not add Functions to it as its "read only". But I see it now in the parent Widget as a "function". how would I go about adding features now to that readOnly?

[remote meteor]

amazing ue5 😆

when ur button in ur W_Button is pressed/clicked

called the event dispatcher

in your parent user widget

[manic hamlet]

I understand that

[remote meteor]

click the selector button

[manic hamlet]

u mean this:

[remote meteor]

there is an add event for the event dispatcher

[remote meteor]

ye

[manic hamlet]

Yeah i understand that so far 😄

[trim matrix]

@zealous moth

[manic hamlet]

But The "Test" function is empty,so nothing will happen,no?

[tawdry surge]

@drowsy thistle you can truncate your values, but depending how your movement is set up that may be easier said than done

[remote meteor]

press the view button

that event will fire

[remote meteor]

when the event dispatcher is called

[manic hamlet]

Wait... by just clicking "New Event Dispatcher" does the "Test Event Dispatcher" already know to call the OnClick-Function like this?

[remote meteor]

you need to connect them

[manic hamlet]

ahhh one sec i think i got it...

[zinc plover]

im having ths error whenever i try to open the game what should i do

[remote meteor]

what did you do last that causes the crash?

[zinc plover]

i compiled an animated blueprint

i knew it has an error

but i didnt expect it would do that

[zealous moth]

so here you could make a new state that plays once and you have a new state of walking/running

or you could run a montage each time you play the detection

[remote meteor]

hm you can try temporary remove the abp.uasset from the content folder in explorer

and try to see if it launches

[zinc plover]

alright ill try thank you

[remote meteor]

dont delete it ya 😅

[manic hamlet]

@remote meteor Thats amazing! Although in my specifc example I will keep the functionality in the Button itself, but for future uses this might be useful!

But it works both ways now.

[remote meteor]

ye

if you need to tell your parent widget to do something

event dispatcher is the best way to do that, since unreal automatically binds the child user widget event dispatcher

there are no bi-direction reference

[manic hamlet]

Yeah I see that now... Really useful 😄

[remote meteor]

it purely depends on how ur parent widget implements the function and the to do

you can have the same button

and place it in different parent

and they behave differently when pressed

[hollow gorge]

hello, is there an internal difference when placing a get reference from a variable like this?

[trim matrix]

ya I tried that already

didnt work

[manic hamlet]

Yeah you could make a "GeneralButton" Widget.... make a Dispatcher called "OnClickDispatcher" and literally use the GeneralButton ANYWHERE and just call the OnClickDispatcher.

[winter tusk]

Guys, how can I create a blueprint actor from selected objects in my scenes ?

[remote meteor]

select them, on the detail panel, should have a blue button called add script something

[last swallow]

Hey guys need some help, i made a horsecart and trying to rotate it that the wheels are standing on ground. So i made a trace by wheel left and a trace for wheel right and got to hit location vectors, now i want to rotate the x-axis of the cart based of the two vectors i got but i dont now how

[remote meteor]

that will convert, say a static mesh to a blueprint holding that static mesh

or you can manually create the blueprint youself then add the assets into it

[zinc plover]

@remote meteor it worked, thank u, really, its really important to me, you just saved all the work ive done

[remote meteor]

you may want to redo the abp if its not too much

and the references

[zinc plover]

yeah maybe hahaha its okay

[zealous moth]

what happened? did it loop?

[winter tusk]

You mean this I think ? https://i.imgur.com/ck8XMj7.png
If yes it tell me to choose a parent class but I don't know what to pick

[remote meteor]

hm select "Actor" to start with

[manic hamlet]

@winter tusk you can shift+windows+S...then make a snippet of whatever you wanna show(it automatically is in your memory) so you can ctrl+v in this chatbox in discord and post images.... way more userfriendly for other people who want to help you,as they can see image immediately 🙂

[winter tusk]

There is no "Actor" parent class

[winter tusk]

Nice thx

[remote meteor]

hmm not sure how ue5 does it

what are the options there ?

[manic hamlet]

np imgur is so 2010 😄 😄 😄

[remote meteor]

here

the second one, what is it?

[winter tusk]

"New C++ component"

[remote meteor]

😅

[winter tusk]

xD

[remote meteor]

im not very sure where they hide that button in ue5 but

i think you can create a new blueprint

then add a static mesh in within

and replace the current one

[trim matrix]

never played

[remote meteor]

@winter tusk can you check what button this is? 😅

beside the + Add button

[remote meteor]

Ah yes

Thats it

😅

[winter tusk]

it's better but then I have this

[remote meteor]

Actor

[winter tusk]

I can't select it

[trim matrix]

@zealous moth

...

[remote meteor]

Eh really?

[trim matrix]

😠

[zealous moth]

that should work

do a print string

[winter tusk]

When I select it it hides the "select" button

ok found it, I need to select "child Actors"

in the first menu

[trim matrix]

didnt work

[winter tusk]

Thx for your help

[trim matrix]

maybe its because i dont have the mesh node

[remote meteor]

Hm check the blueprint after creation

[trim matrix]

%%

[zealous moth]

the print string didnt work??

[trim matrix]

arghhhhhhhhhhhh

[trim matrix]

no

[remote meteor]

The staticmeshcompoenent should be the root component

While the base class is an Actor

If yes then yeah thats it

[zealous moth]

then it isn't getting played at all, somewhere in your logic, this is skipped

[trim matrix]

?

[languid quail]

i think im giving up for now i don't get it to work sadly

[manic hamlet]

@remote meteor FYI: thats that button 😄

Done with "work" today though,so thanks again 😄 see ya next time i got a question LOL

[zealous moth]

oh wow yes

[trim matrix]

it not right

the object plug?

where

this never works

even this it doesnt work

[vapid comet]

if i had a health actor component and a DOT actor component how would i call variables from one to another? Specifically i want to call the actor's current health in the DOT component

[faint pasture]

The DOT component gets attach parent, gets component by class (HPComponent), and applies damage or healing to it during its Apply event

[faint pasture]

Or whatever the owning actor of a component is, Owner maybe?

[trim matrix]

so i need to cast

[faint pasture]

what's with everyone having a boner about casting

where is this coming from, the idea that "cast" is some sort of "reach out and get whatever you need"?

[trim matrix]

so what do i do

im too visual

[faint pasture]

I mean what's the source of all the newbies misusing the term? Is there some big tutorial somewhere that gets everyone off on the wrong foot?

[trim matrix]

dont understand whats your saying

[fiery swallow]

Is your mannequin an actor ?

[trim matrix]

its an AI

[fiery swallow]

Not exactly what I meant :>

[faint pasture]

We get that. Where do you put something in that variable? Where do you set it?

[fiery swallow]

@trim matrix if you wanna try it, use get actor of class to get the first actor in the first mannequin in the world, set it as your mannequin variable and then try to run that code... it'll quickly show you what you're missing

Maybe just put only one actor in the world though if you do try that out, the idea is you need a reference bud.. which is what get actor of class will get you .. it's just not a reliable way when you're going to have many

[spice estuary]

I just ran into an issue with a BP child of my new C++ character class
And I resolved it by reparenting it to the ACharacter class and then re-reparenting it back to my C++ character class
And I was wondering if someone could explain why doing this reparenting back and forth somehow "fixes" the initial breakage of the reparenting?

[odd ember]

probably better to ask in #cpp about that

or on the epic forums

where someone can explain why this bug still persists

[spice estuary]

Overall it sounds like reparenting a BP is a bit dangerous in general then 😅
I'll post this to #cpp channel and see - thanks!

[odd ember]

I mean it kind of is, I'm still dealing with a corruption from a time where I reparented something I shouldn't have

[grand wigeon]

Does someone know some good tutorials for how to achive this kind of installation with blueprints? https://youtu.be/QIfbRKeB0lI

[barren sonnet]

Im trying to snap components down to the ground using a construction script with a specific tag but they are coming in on their side. Any idea why this might be happening ?

[faint pasture]

?

[sonic crest]

why does this keep popping up when I save all?

[faint pasture]

Cuz you haven't saved the level

[sonic crest]

I did

I always save all and I got the level saved, sometimes when I save all this pops up

even saved the level alone

[jolly radish]

anyone got any idea what i can put here?

[sonic crest]

I'd use a custom event or from event begin play with a timeline on loop rather than a tick

[jolly radish]

okok

[sonic crest]

you need to get what references the cast

who is or what is casting to it

you can get "get actor of class" not sure if that's what you're looking for

[faint pasture]

Anything that'll give you a Target spawner reference. Also why are you doing that on tick with a delay? What are you trying to accomplish there.

[jolly radish]

done this

@sonic crest

how do i make it update

[faint pasture]

Quick question, why is the text render separate from the spawner?

[jolly radish]

wdym

[faint pasture]

Why do you have a spawner actor and then a separate render actor that shows the spawn count?

[jolly radish]

idk :(((

[faint pasture]

Just add the text render component to the spawner, if that's what you want to have happen. Where do you want the text to be rendered in the world?

[jolly radish]

gotcha

[radiant grove]

Hey hey, anyone here know much about blueprints and level_sequences?

[grand wigeon]

Sorry I forgot the link https://youtu.be/QIfbRKeB0lI

[radiant grove]

I am trying to figure out , via blueprints, how to get the Camera cut to bind to the MainCam

[austere aspen]

why don't my doors open and close independently of each other? they open and close with the Interact input action, and also close when leaving a box collision, but for some reason they both open and close the first door, but only the interact action does, leaving the second door's collision doesn't close the first one.

[odd ember]

hard to say without seeing some code

[austere aspen]

fair. the Get All Actors of Class is on BeginPlay in the Player Character. The Interact InputAction just calls the Open Door custom event and makes the player look at said door. The Open Door custom event itself is more or less the same as this tutorial (https://www.youtube.com/watch?v=hZHj5CtonQA&ab_channel=CobbDev), with the begin and end overlaps being what finds which way to open the door, and also to set if the player can open it or not and to close the door and set the visibility of the widget.

[odd ember]

is the get all actors of class just for testing?

[austere aspen]

I was originally wanting to have a tag or something to mark an actor as "interactable" so the InputAction just calls a function from that specific actor if it's the one the actor is in its collision of, but couldnt find a way of doing it

[austere aspen]

yes, I also tried Get Actor of Class but that had the same effect. Changing the index of the Get changes which door is affected

[odd ember]

my guess is the logic to find which side of the door is borked

[austere aspen]

dunno why that would be the cause for this, I was under the assumption it'd be the way I was getting the door reference in the Player Character, seeing how the index of the Get changes which door is affected, but I have no idea how else to get the reference aside from casting maybe, but then what to put in the wildcard for that?

[odd ember]

you have open door twice

once on component end overlap (assuming that's your trigger) and once on interaction

[austere aspen]

yeah, one for opening, one for closing

[odd ember]

so you don't think that's at the core of your issue?

[austere aspen]

i mean, even taking away the open door in the end overlap, the interact open door issue still remains

[odd ember]

try with breakpoints

[odd ember]

at least you've isolated the issue to that point then

you can double check if the inverse is true

[marble tusk]

The issue is you're getting all actors of class and only using the first actor in the array

[austere aspen]

switching back to Get Actor of Class still has this issue

[faint pasture]

You shouldn't be getting door or doors. You should be getting the nearby door if there is one.

aka

some sort of hit/overlap test

[odd ember]

I don't think I'm seeing the entire picture. most likely the architecture breaks down somewhere. but try with breakpoints and see what happens

[faint pasture]

When you open a door, you open the one within reach. Not the door or doors that exist on the map, no matter the distance.

[austere aspen]

using breakpoints just breaks when the action happens, it doesnt say why a door is doing that instead of the other one

[faint pasture]

It's because of how you're choosing your door

you're choosing the first one in the world.

instead of the one you're next to

[austere aspen]

so use a sphere trace or something similar?

[faint pasture]

yes

Do you have a general Interaction mechanic or is doors all there is?

[austere aspen]

doors is currently all there is but I do want to have a general interaction system

[faint pasture]

OK so I'd start with making a function on your pawn ChooseActorToInteractWith

[austere aspen]

I did try doing a sphere trace but couldnt get my head around the different kinds and which I should use for a certain list of actors

[faint pasture]

You can do a line trace instead, however you wanna do it

if you want really accurate aimed interaction like Skyrim that'd be a line

[odd ember]

I mean the simplest thing is to use the overlap as the one actor that will be interacted with

[faint pasture]

if you want a more general auto-aimed selection I'd do a sphere trace then do some sort of filtering and selection.

[odd ember]

that way you don't need get all actors of class or anything else

[faint pasture]

Just Trace in some way or get overlapping actors or whatever -> select which actor to try to interact with

[austere aspen]

yeah, I'll do that then, but something I always found odd was in tutorials people would just cast right after a trace, which left me wondering how to do multiple casts and such from one trace

[faint pasture]

Do you know what a cast is

[austere aspen]

only as much as most people say, a way to get a reference of an actor, though I'm assuming that's not the case

[faint pasture]

No

Cast is a question. Is Object A of class B?

Is this Animal a Dog? (I want it to bark)

won't make much sense if it's a fish

but you need to check since you were just given an animal

Is this Actor a Door? (I want it to open)

"No, it's a bullet" ok nvm

Since traces etc give you Actors, you sometimes gotta check if they're the class you care about

[austere aspen]

so is the Cast Failed exec like the False of a Branch?

[faint pasture]

ye

[austere aspen]

ahhh

[faint pasture]

Every day with this casting business lol

ok so

make that function like I said

make a function that just returns an Actor

[jolly radish]

so this just isnt working how its supposed to

the "head" goes somewhere completely different

[faint pasture]

call it ChooseActorToInteractWith, and have it return an Actor. Do your work for choosing what to try interact with inside that function.

[faint pasture]

Head location updates as the timeline plays

so you're constantly lerping FROM a different position

resulting in fucky movement

[austere aspen]

wait what do you mean by "returns an actor"? the actor of which the trace is hitting?

[jolly radish]

it supposed to go to the location setout right?

[faint pasture]

Functions can return things. Return an actor reference/pointer (the blue thing)

Either have it be null for a failure or also return a boolean

[austere aspen]

yeah but like, what goes into the actor return?

[faint pasture]

You fill that in. do your sphere tracing or line tracing or whatever (You can start with get actor of class to test it)

That's the whole point. Give yourself the skeleton of the code (a function that returns what you want to interact with), then flesh it out.

[jolly radish]

did this in an attempt to fix it by giving it a constant variable, did not fix it :(

[faint pasture]

What's it doing?

[austere aspen]

so just to be clear, are you saying to have a function like the first image, or like the second?

[jolly radish]

moving here

when it should be moving here

[faint pasture]

Those are the same, just the 2nd image is less fleshed out

[faint pasture]

You're moving to head + Destination, not to destination

[faint pasture]

So it's a local move, you'll move the same distance no matter where you start instead of moving to the same spot in the world

[jolly radish]

destination is only relative to the head tho no?

those are not the real world locations of it

only the location relative to the head

[austere aspen]

ah I got it, it works. Thanks

[faint pasture]

So as you develop you'll want to flesh that function out more. You might notice right now you can only return one actor from that trace. You'll eventually wanna do a multi sphere trace (or use an overlap collider) and do some loop selecting which actor you want to talk to. It'll get bigger and more complex but the end result is the same, it returns the actor you want to interact with.

That's a good way to develop your functionality. Start with the function or the data, and fill it in.

[austere aspen]

when it hits something else first it then doesn't hit the door

[faint pasture]

You'll need a multi sphere trace and a loop where you choose what you want to interact with

[austere aspen]

alright
